runtime/cgo: retry pthread_create on EAGAIN for OpenBSD

2016-12-05T21:15:05+00:00

For reasons that I do not know, OpenBSD does not call pthread_create
directly, but instead looks it up in libpthread.so. That means that we
can't use the code used on other systems to retry pthread_create on
EAGAIN, since that code simply calls pthread_create.

This patch copies that code to an OpenBSD-specific version.

Also, check for an EAGAIN failure in the test, as that seems to be the
underlying cause of the test failure on several systems including OpenBSD.

Fixes #18146.

runtime/cgo: save correct floating point registers on s390x

2016-11-23T22:06:06+00:00

When transitioning from C code to Go code we must respect the C
calling convention. On s390x this means that r6-r13, r15 and f8-f15
must be saved and restored by functions that use them.

On s390x we were saving the wrong set of floating point registers
(f0, f2, f4 and f6) rather than f8-f15 which means that Go code
could clobber registers that C code expects to be restored. This
CL modifies the crosscall functions on s390x to save/restore the
correct floating point registers.

Fixes #18035.

runtime/cgo: fixes for calling sigaction in C

2016-11-16T23:10:33+00:00

Zero out the sigaction structs, in case the sa_restorer field is set.

Clear the SA_RESTORER flag; it is part of the kernel interface, not the
libc interface.

Fixes #17947.

runtime/cgo: use libc for sigaction syscalls when possible

2016-11-16T05:38:38+00:00

This ensures that runtime's signal handlers pass through the TSAN and
MSAN libc interceptors and subsequent calls to the intercepted
sigaction function from C will correctly see them.

Fixes #17753.

runtime/cgo: correct type declaration for Windows

Newer versions of gcc notice a type mismatch and complain.
Fix code to match documented signature in MSDN.
Trybots say this still compiles with the older (5.1) version
of gcc.
